Abstract: A seat using a pair of walking sticks. A seat member is formed adjacent the top end of the walking sticks. The walking sticks are releasably attached to one another adjacent top ends of the walking sticks so that seat members together form a seat, and the walking sticks diverge from the seat to form a two-legged stool. Each seat member is pivotally mounted to the top end of the respective walking stick for movement between a deployed position in which the seat extends at an acute angle from the top end of the walking stick, and a stowed position in which the seat extends alongside the respective walking stick.

Abstract: The equipment (10) comprises a pair of walking sticks (12,14) or the like that are arranged so that they can be connected together to form a two-legged stool.

Abstract: A method is disclosed for attaching a ferrule to a dragline rope. The method comprises locating the dragline rope in a die of a die-press, locating over the dragline rope a ferrule that is lined internally with a deformable material, and forcing the ferrule longitudinally through the die. The ferrule is caused to be internally expanded and be extruded back over the dragline rope, causing the lining to deform directly against the dragline rope and fastening the ferrule to the dragline rope.

Abstract: The present application provides systems, apparatus, and methods for providing high quality printed corrugated sheets and webs through the use of a variable sleeve offset press. In one embodiment a method is provided comprising the steps of: printing a paperboard web to provide ink to the linerboard web. The printing step may comprise using an offset printing press having variable repeat length. The method may further comprise rewinding the printed paperboard web onto a roll; providing the printed paperboard web to a high speed corrugation machine via the roll; laminating the printed paperboard web to a fluted web thereby producing a printed corrugated web. The method may further comprise applying heat to at least one of the printed paperboard web and the fluted web which causes heating of the ink on the paperboard web printed thereon by the offset printed press.

Abstract: The present invention is an automatic gain control system for use with a multiple wavelength laser LIDAR system that transmits sets of time-separated interrogating signals to generate sets of time-separated return signals. A comparator defines a plurality of unique peak amplitudes and a corresponding plurality of unique binary words associated therewith. The comparator receives each of the laser LIDAR system's return signal from an i-th set thereof and outputs a binary word indicative of a peak amplitude achieved thereby. The binary word is one of the plurality of unique binary words. A memory has each of a plurality of address locations defined by one of the plurality of unique binary words. Each address location stores a unique gain value. An adjustable gain amplifier has a signal input for receiving each return signal and a gain adjustment input coupled to the memory.

Abstract: A grenade machine gun or other weapon which employs superelevation of the barrel comprises a barrel unit and an aiming system mounted upon a support. The aiming system is mounted to the weapon and the support by a coupling unit. The aiming system comprises an imaging and display unit for displaying an image of a scene including a target, angle encoders for providing a signal representing displacement of the imaging unit in elevation relative to the support, and a control unit, e.g. a computer, for selecting either of two states for the coupling unit. The first state entrains the imaging unit to move with the barrel. The second state secures the imaging unit to the support and allows the barrel to move relative to both, i.e. during superelevation of the barrel. The coupling unit may comprise a first part connected to the weapon for rotation in elevation with the barrel unit and a second part connected to the imaging unit.

Abstract: The method of operating a two electrode electrochemical detector cell in which the cell is connected to an external current measurement circuit through a cyclically operated switch which alternately opens and closes the connection between the cell and the external circuit. The cell is operated without bias potential. The peak current obtained from the cell after closing the connection to the external circuit may be measured immediately without any delay for transient current to decay. Means are disclosed for automatically compensating for background current error in the cell current measurement.

Abstract: A mono-lobe tracker is described for tracking a target emitting radio signals incorporating an antenna, a circuit for sequential lobing, a radio frequency amplifier, a mixer, an intermediate frequency amplifier, an amplitude modulator detector, and integrators for storing the amplitude signals corresponding to predetermined off boresight positions, means for taking the difference of two integrators indicating the boresight error, a motor coupled to the error signal for driving the antenna in response to the error signal and a random number generator for generating at random a plurality of frequencies which are coupled as randomly selected to the sequential lobing circuit. A random number generator is also described incorporating a noise diode, an amplifier, a voltage comparator and a counter.

Abstract: A digital frequency synthesizer includes an oscillator and a variable frequency digital divider, whose divisor N is switchably selected for dividing the oscillator frequency. A counter accumulates a count related to the number of cycles of the divided oscillator frequency occurring in a unit time, with this number being used to set the divisor of a second digital frequency divider. The oscillator frequency is also divided by the second divider, with the resultant signal having a frequency of N Hz.
